10 animals presumed extinct in the last decade

Liverpool pigeon

The Liverpool pigeon, or spotted green pigeon, is an extinct bird species of unknown origin, although some researchers speculate it might have lived in Tahiti. The only remaining specimen of the bird resides in the Merseyside County Museum, and scientists say it's likely that the species was close to extinction before European exploration began in the Pacific. The International Union for Conservation of Nature assessed the species in 2008 and declared it extinct, but the reasons for its extinction remain unknown.
